Arizona Spam Call Complaints Climb 29.8% in 2025

Live Poll

Have spam calls gotten worse for you in the past year?

Arizona residents filed 410,521 complaints about unwanted and spam calls between October 2020 and September 2025, according to an analysis of the FTC's National Do Not Call Registry data. The findings are retrospective and based on complaint filings, not a new product or regulatory action.

Why it matters

Arizona's per-capita complaint rate sits well above the national average, and fiscal 2025 complaints climbed after two years of decline, suggesting unwanted call volume is not easing for residents. The trend points to continued pressure on call-blocking and carrier-level filtering tools as robocall methods evolve.

The figures are complaint counts normalized per 100,000 residents, which allows comparison across states of different sizes. Arizona ranked 13th nationally in total complaints for the five-year period, while Delaware had the highest per-capita rate at 5,736.4.

The players

Federal Trade Commission

The federal agency that operates the National Do Not Call Registry and publishes the Data Book on consumer complaints about unwanted calls.

U.S. Census Bureau

The federal statistical agency whose 2025 resident population estimates were used to calculate per-capita complaint rates.

The details

The analysis draws on complaint records that consumers submit to the Federal Trade Commission's National Do Not Call Registry, a database of complaints about telemarketing and robocalls. Researchers divided each state's complaint totals by its resident population from 2025 Census Bureau estimates to produce a rate per 100,000 people. That normalization is what allows a state like Arizona to be compared against others with very different populations.

October 2020 to September 2025: five-year period covered by the complaint analysis.
Fiscal 2021: Arizona complaints peaked at 141,601.
Fiscal 2023: Arizona complaints fell to a five-year low of 50,005.
Fiscal 2025: Arizona complaints rose to 74,752, up 29.8%.

The Tech Race

Complaint data from the FTC Data Book is one of the main public measures of how well call-blocking and carrier filtering are keeping pace with robocall operators. Arizona's rebound in fiscal 2025 suggests the problem is still growing faster than enforcement and filtering can suppress it in some states.

Arizona residents who receive frequent spam calls can keep using call-blocking features on their phones and register numbers with the National Do Not Call Registry to reduce legitimate telemarketing. The data does not indicate any new tool or rule taking effect, so current options are the ones available today.

The takeaway

Watch the FTC's next annual Data Book release to see whether Arizona's fiscal 2025 increase continues or reverses in fiscal 2026. A second consecutive rise would indicate the recent uptick is a sustained trend rather than a one-year spike.
